Matter of fact, my Chevelle ran quicker than EVERY n/a 454, 496, 502, GM's 720HP 572 and most 540's regardless of which head they ran, in a similar Chevelle here in Division 1 brackets, just saying.
BTW, the devil is in the details and the performance that HP Hunter speaks of also comes by way of a $6,000 Coan XLT 350 trans backing up that 496. 
Just saying.  |
Ed, forgot one thing here, my customer ran consistant 9.70s in his full weight small tire nova at Atco for two years strait with my 049 heads. 505 CID.
